The stamping process for CDs and vinyl are pretty similar. You have to make a mold with all the bumps & features first, and then stamp it on to the plastic. In the case of pressing vinyl, the bumps can have variable size to make the needle move, but CD pits are of definite size for the 1's and 0's. The molded plastic on a CD is later covered in aluminum to make the pits reflective to the laser.
